Ultrasonic level sensor is a common device
for measuring liquid level, and has wilder application area. The ultrasonic
level sensor has the characteristics of easy installation and non-contact
measurement, and is not affected by the viscosity and transparency of the
liquid. At the same time, the ultrasonic level sensor is transmitted by air,
and its measurement accuracy is affected by ambient temperature, ambient
humidity, medium temperature, medium pressure, wind speed and the like.
According to the characteristics of the ultrasonic, the actual one is more
suitable for occasions where the precision is not high and the working
environment is not bad.

First. The water treatment industry.

Water treatment industry, including sewage
treatment, tap water, pure water manufacturing and other occasions. The medium
to be measured is basically sewage and clean water, and the accuracy of
measurement is not high. Moreover, the working environment is basically not
highly corrosive, there is no electromagnetic interference, and most of them
work in the open air. At most, the waves in the water inlet are large, or there
is a small amount of foam on the water surface.

Second. Water and hydrology industry.

In the water conservancy and hydrological
industries, in the early years, the water level changes were mostly used at the
gates. In recent years, due to the increased investment by the state in the
water conservancy industry, mountain flood warning and water level rainfall
monitoring are required in the small and medium-sized river basins. These
occasions basically require 12VDC power supply and 485 output. Because they are
all measured on the water surface, there is no requirement for the emission
angle of the ultrasonic level sensor, and there is no volatility or foam.

Third. Farmland irrigation.

With the lack of water resources, farmland
irrigation has begun to monitor water level and flow. They are generally
carried out on relatively wide channels, and small channels generally do not
require measurement. Common channel widths are more than 1 meter.

Fourth. Chemical companies.

Mainly for anti-corrosion and
explosion-proof ultrasonic level sensor. The liquids of chemical companies are
measured by ultrasonic waves and are basically in storage tanks. For example:
sulfuric acid, hydrochloric acid, liquid alkali, toluene, xylene, olefins,
ammonia, acetone, and the like. These occasions can be solved with an
ultrasonic level sensor.

If it is in the reaction kettle, the effect
of using the ultrasonic level sensor will be poor because of the effects of stirring,
high temperature, vacuum, steam, mist, foam, and the like. It is better to use
radar level gauge, pressure level gauge, RF admittance level gauge, etc.
